Gov. Jon Corzine's (D) campaign can now point to a second poll showing the Democrat pulling ahead of Chris Christie (R). A Greenberg Quinlan Rosner Research poll conducted for Democracy Corps gives the incumbent a three-point lead.

General Election Matchup
Corzine 41 (+2 from last poll, 9/22-23)
Christie 38 (-2)
Daggett 14 (+3)
Undecided 7

For the first time, GQR finds that more Democrats say they'll support Corzine than Republicans who say they'll back Christie, showing that the governor has consolidated his base. Christie's fav/unfav split is 30 / 42, a net drop of 10 points. Corzine is viewed favorably by 37 percent of voters, and unfavorably by 46 percent.

The mammogram issue seems to be playing a big role in swaying women voters. From the polling memo:

Christie has lost significant ground with women, especially independent women. He now posts a net favorability rating of -19 with women, down from -7 two weeks ago. Among independent women, the drop is even more pronounced: from -7 two weeks ago to -34 today, with half of independent women giving him an unfavorable rating. This has clearly benefited Corzine in the vote as the governor now leads among women by 14 points (up from 6 points two weeks ago).

The telephone survey was conducted from October 6-7, 2009 among 614 likely voters. The margin of error is +/- 4.0 percent.
